Subject: 24.2.93;
	auto-generated latin-ltx mappings make suboptimal glyph choices
Date: Wed, 13 Mar 2013 18:37:10 -0400

After the change http://bzr.savannah.gnu.org/lh/emacs/emacs-24/revision/107803:

    * leim/quail/latin-ltx.el: Auto-generate some of the entries.
    (latin-ltx--ascii-p): New function.
    (latin-ltx--define-rules): New macro.
    (define-rules): Use it.

Certain latin-ltx rules (those for diaeresis etc) are autogenerated
based on a pattern match of character names, this has the unfortunate
side-effect of sometimes making undesirable (at least to me) choices of
glyph.

For example, on this system if I type \"e it prefers CYRILLIC SMALL
LETTER E WITH DIAERESIS (the equivalent is true for A, O, etc.) --
presumably because this is the first character that matches the pattern
specified -- it's rarely the character I want though, and it's
impossible to get completion access to others (or possibly enter them at
all, I'm not familiar enough with quail to say, I've never needed to be
before)

Reverting the above change restores things to defaulting latin, as it
used to.  It'd be nice to either get the old behaviour back, to get the
ability to cycle the possibilities, or to have the ability to specify
which alphabet should "win" to resolve conflicts, whichever is more
appropriate.
